WINDOW-CLEANER.

Specification of Letters Patent.

Patented Sept. 1, 1908.

Application filed 0mm 18, 1967. Serial No. 898,097.

To all whom it may concern:

Be it known that I, GEORGE O. DwIeH'r,.a citizen of the United States, residing at Red Bank, in the county of Monmouth and State of New Jersey, have invented certain new and useful Improvements in Window-Cleaners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to window cleaners, and the object of my invention is to produce such a cleaner that will-be simple in construction, certain in action, cheap to manufacture, and which will provide means whereby the corners of a window pane may be gotten at and thoroughly cleaned.

A further object of my invention is to provide such acleaner with means whereby the rubber, used in drying the window, is not liable to be cut in two while being used,'and Whereb each corner of the rubber strip may be use as a cleaning surface.

To these ends my invention consists in the combination of parts more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like letters indicate like parts in all the views, Figure 1 is-a perspective view of my window cleaner showing the cleaning member contacting with the window ane. Fig. 2 a plan view of the same part y broken away, and partly in section, and Fig. 3 a cross sectional view taken on the line 33 of Fig. 2 showing the rubber drying member contacting with a window pane.

A represents a cylindrical liquid receptacle or tank having a handle B attached to its under side. This liquid receptacle is revided with a slot or opening C forme( by turning the metal of the said receptacle bac upon itself, as shown, and into this slot I secure by solder, or otherwise, the open bottom trough like receptacle D as shown. This receptacle has its side walls extending downwardly a considerable distance into the recepltacle A as above shown in Fig. 3.

represents the core of the cleaning member F, and G represents a suitable fabric, or

other material, surrounding said core, and adapted to take up water from the tank A by capillary attraction, as is well known. The

cleaning member is tapered in cross section, and is made'to fit the trough D.

H represents a bracket secured to the tank A, and provided with a clamping member J having the fiat wall J, through which pass the screw or other fastenings K as shown. Betweenthis clamping member J, and the bracket H, is firmly clamped the rubber drying member L. The upper lip M of the clamp J is inclined at an angle of about 135- ily turned end for end and may also be turned over laterally, and again turned end for end and, thereby when fastened in these various positions each of the four edges may be used. That is to sa there are four posi tions in. which this sing e rubber strip may be clamped, and in each position a new edge is available for contacting with the lass. The slightest crack due to wear of t e rubber, causes a streak on the glass and there'fore .when an ed e becomes worn it is of little use.

Consequent it is found very desirable, in ractice, to e able to turn the rubber strip into as many positions as possible, and thereb to utilize as many wearin edges as possib e before the same is to be' discarded. I prefer to emplo felt for the covering G, on my core E, and flare both the core and the felt covering outwardly at each end ofthe cleaning member F, as shown at N. The object of thus flaring the ends of this cleaning member, is to enable the same to enter the corners of the window, and thereby clean those places that have been heretofore so diflicult to reach. Also, my felt cleaning member F serves both as a sto per for the tank A and for a wick, for felt is a material which readily absorbs water, and keeps moist as long as any water is brought in contact therewith.

0 re resents a cap of an suitable material extending about an eighth of an inch over the cylinder at each end, and which protects the corners of said cylinder against knocks and which provides a rounded edge on said cylinder, and thereby revents the same from cutting .the win ow sash. I have found from practical experience that when only the end piece P is soldered intothe end of the cylinder, and the cap 0 not employed, the cylinder is liable to mar and injure the window sash, especially if the operator is not careful.

I consider the an les at which the brackets II and the trough and consequently the angles at which the drying stri L and the cleaning member F are laced re ative to the longitudinal plane passing through the handle B, to be of'importanee, in that they enable me to bring a greater portion of the surface of the cleaner F into contact with the glass, than it would be possible to do, were any other angle adopted for the said cleaner F. And this is because the operator may readily approach the handle B toward the glass, or recede it therefrom, and thereby turn the said cleaning member F on a pivot, as it were, and utilize a greater ortion of its surface for cleaning'than woul be the case were the handle B parallel to the glass when I, also, attach a special the device is in use. importance to the angle at which the bracket K, and consequently the strip L, is inclined to the handle B. By making this angle oblique and substantially 25 degrees, as above stated, I am also enabled to move the said strip about a center as it were, and to readilyexert a considerable pressure on the said stri in a direction toward the center of the tan A, and thereby take considerable pressure from the strip in a direction at right angles to its surface. That is to say, I have found in practice that where the strip is severely bent at right angles to its surface it soon 'breaksand cracks at the edges of its holding clamp, and is consequently worn out and worthless before its edges are worn. I, also, attach considerable importance to the angle of 135 degrees that the portion M of the clamp J makes with the flat surface of the said strip, for it enables the said strip L to be bent down a considerabledistance without being cut or ruptured by said holdin jaw. I found, in-praetlce, that-a stripheld y a jaw at this inclination lasts much longer, than a strip which contacts with the same at an ang e of, say 90 degrees. a

It will be seen from Fig. 2, that the strip L extends out slightly b yond the extreme ends of the tank A, an beyond the extreme ends of the bracket H, and the clamp J.

These extreme ends Q of the strip which are not-backed u by any metal, are found exceeding] use 1 in getting into the corners of the win ow sash, and are very effective, therefore, in securing an absolutely dry surface of the window pane.

In operation, the cleaning member F is recleaned, the glass is dried and polished by applying the rubber edges of the strip 1 t iereto.

Owing to the fact that the walls of the trough D extend down into the tank A as shown, water may be kept from the felt G, when desired, and the said felt allowed to become more or less dry in cleaning the window. In other words, after the felt has been thoroughly moistened by so tipping the tank as to allow the water to come in contact therewith, and after the window has been washed by this wet felt, by the simple device of not further ti )ping the cylinder the water may be allowed to be squeezed out of the felt G, and the same become partially dry, and thereby act as a partial drying material or agent for the window, and get it into better condition for the rubber strip which comes after.

Having now described my invention what I claim is 1. In a window cleaner the combination of a liquid receptacle, A, )rovided with a cap at each end and an ori ice extending longitudinally thereof. a cleaner, F, provided with a core tapered in cross section, and having flared ends, extending be ond the ends of said rece taele and a hand e attached to said receptac e, substantially as described.
